# 7.3. Input Devices

You can use several input devices with the X Window System (and thus with KDE). You can change their settings here:

## 7.3.1. Keyboard

Here, you can set whether a character is repeated when you keep pressing its key. If you have a bad keyboard and need the clicking after you hit a key, you can also turn on the key click volume.

## 7.3.2. Mouse

The Mouse is the most frequently used pointing device around, and for the majority of computer owners, the most intuitive method of navigating through KDE. (For some owners with bad mice, it is also a reason for visiting the doctor very often, see Drag & Drop for information.)

Acceleration

  Sets the speed of the mouse. The higher the setting, the faster your mouse will move around the screen.

Threshold

  Threshold is the distance the pointer must move (in a small amount of time) before accelerated movement occurs. 0 disables it.

Try to experiment with these settings; the right combination will allow you to point exactly on short distances and to move fast over long ones.
